I'm sure you reproduce these quotes in good faith, but you ought to know they are not necessarily what they seem. The Darwin quote is a particularly craven quote mine: he was expressing empathy with those of his readers who found it difficult to imagine how such a thing as an eye could evolve by stages; effectively putting himself in their place so that he might more readily take them by the hand and show them how such evolution may occur, with ample supporting evidence from the natural world. I refer you to the Quote Mine Project for further edification.
